The Office of Foreign Assets Control (OFAC), a part of the U.S. Department of the Treasury, has announced updates to its Specially Designated Nationals and Blocked Persons List. This action blocks all property and interests in property of the listed individuals that fall under U.S. jurisdiction and generally prohibits U.S. citizens and businesses from conducting transactions with them. One individual recently added to the list is Antal Rogan from Hungary, designated for involvement in corruption and misappropriation of state assets. More details, including the full list and sanctions programs, can be found on OFAC's website.
Simple Explanation
The U.S. Treasury's Office of Foreign Assets Control (OFAC) has decided to block certain people's things, meaning Americans can't do business with them, because those people are involved in bad things like stealing from their own countries.
